Say I have a set s = {1, 2, 3, 4, 5}. Can I remove the subset {1, 2, 3} from the set in just one statement (as opposed to calling s.remove(elem) in a loop)?

Given a set, the task is to write a Python program remove multiple elements from set. Example: Input : test_set = {6, 4, 2, 7, 9}, rem_ele = [2, 4, 8] Output : {9, 6, 7} Explanation : 2, 4 are removed from set.
clear() The clear() method removes all elements from a Set object.
Python Set clear() The clear() method removes all items from the set.
Remove Multiple elements from list by index range using del. In this approach, we will use the del keyword to delete elements of a specified index range from the list. This function will delete all the elements from index1 to index2-1.
Yes, you can use the set.difference_update() method (or the -= operator):
>>> s = {1, 2, 3, 4, 5}
>>> s.difference_update({1, 2, 3})
>>> s
{4, 5}
>>> s -= {4, 5}
>>> s
set()
Note that the non-operator version of difference_update() will accept any iterable as an argument. In contrast, its operator-based counterpart requires its argument to be a set.
